IMPROVEMENT IN cAs-RE'GULATORS.

Specification forming part of Letters Patent No. 1924.34, dated November 20, 1877; application led March 9, 1877.

To all whom it may concern:

Be it known that I, JOHN l?. WARNER, of Baltimore city, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Gas Regulators or Governors; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled 'in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a gas regulator or governor that is very simple in its construction, durable, and not likely to get out of order.

The invention consists of adiaphragm, governor, or regulator, having its lower end or receiving-nozzle made of con ical or tapered shape, into the upper end of which a cup-valve, of slightly conical shape, iits, and which is weighted, by shot or other suitableweights, to the pressure desired. An auxiliary or secondary valve is arranged a short distance below the upper valve, by which the action of v the regulator becomes more sensitive, as a greater surface is exposed to the gas.

The diaphragm is held in place in the shell between the cap and case by a packing-wire,

' which fits into suitable, grooves in the upper and lower edges or faces thereof, and bywhich it is clamped in position. The cap or flange is screwed down onto the outside of the shell, instead of being held by the usual screws or bolts, all of which will be more definitely de-y scribed in the following specification, reference being had tothe accompanying drawing, in which- Figure l represents a vertical cross-section of my governor or regulator. Fig. 2 is a bottom view, showing the guide for the valvestem, Svc.

In the drawing, Ais the outer shell or case, made of any suitable material, having its lower end tapered or conical, and into which the cupvalve B iits, and closes the entrance-opening when drawn to its seat by the diaphragm C, which is connected to the valve by the hollow stem D. A secondary or auxiliary valve, B', is arranged a short distance below the valve B, and also of cup shape, and made of thin metal, the object of which is to give a greater exposed area than when one valve is used to be operated upon by the gas. The valve becomesthereby more sensitive, and will act quicker.

On the upper side of the diaphragm is arranged a cup or'receptacle, E, into which shot or other weights are placed, to weight the valve to the desired pressure.

The diaphragm C is clamped between the cap or flange F and the upper edge of the shell A by a packing-wire, a, which iits, into recesses in the upper and lower faces of the cap and shell, and, as the-cap F is screwed down, it firmly clamps the diaphragm without the use of red lead or other packing material. Into the lower end of the shell is screwed a guide-piece, b, to which is secured the upright c, upon which the hollow stemof the valve fits, and is guided in its up-anddown movements as` the pressure increases or decreases.

To suit different sizesof gas-pipes and meters, and compensate for different sizes of governors, I make use of a peculiar-shaped coupling-nut, which has dii'erentsized openings to it them, and for which I desire to make a separate application for Letters Patent, and said nuts are shown in dotted lines in the drawing.

The operation is as follows: The valve being weighted to the desired pressure intended, and gas-being admitted through the lower end, the gas will openl or close more or less the valves as the said gas impinges against the diaphragm C when the pressure increases or decreases, as will be readily understood by those conversant with the art.

The advantages of my improved governor or gas-regulator are, that it is very simple in its construction, not liable to get outof order, it can be furnished at a very small cost, it is reliable, and there is-no danger of leakage by the use of the wire packing. It is also much more sensitive than any other valve.

Having thus described my invention, what I described.

2. In the'gas-regulatorherein described, the recessed faces of the shell A and cap F, in comnation with the diaphragm C and packing- Wire a, all constructed and arranged as shown and described.

3. The governor or gas-regulator herein de- Y scribed, consisting of the shell A, double-cup valve B B', stem D, diaphragm @Weight-cup E, recessed cap F, and recessed shell A for the packing-wire a, all constructed and arranged substantially as shown and specified.

In testimony that I claim the foregoing as l my own I hereby aiiix my signature in presence of two Witnesses.

JOHN P. WARNER.
